The Descent X30 is Garmin's wrist-mounted dive computer with a 2.4-inch color screen, large metal buttons sized for gloves, and a housing made partly from recycled ocean-bound plastics. It runs the Bühlmann ZHL-16C decompression model, handles single- and multi-gas dives including trimix, and adds NDL Aware real-time decompression guidance, GPS and a 3-axis digital compass for surface navigation. Its 10 ATM rating and depth sensor to 100 m cover recreational and light technical diving, and the rechargeable battery runs up to 30 hours. Against smaller air-integrated rivals it wins on screen size and readability but gives up air integration and a slimmer profile.

The Garmin Descent X30 is a wrist-mounted dive computer with a 2.4-inch color display. The display shows depth, NDL and ascent rate. A flip-screen mode lets you set the orientation for left- or right-handed button access.
The case and bezel are made of fiber-reinforced polymer from recycled ocean-bound plastics. The four large metal buttons are inductive and leakproof, and they work with gloves. The lens is chemically strengthened glass, and the dive band is hinged silicone.
It supports single-gas and multi-gas dives, including trimix. NDL Aware provides real-time decompression information, and planning uses the Bühlmann ZHL-16C model. It also offers surface interval tracking and customizable safety stop and deep stop alerts. Integrated GPS lets you mark entry and exit points, and a 3-axis digital compass handles navigation. It does not support air integration or tank pressure monitoring.
